"Trollius" is a
genusof about 30 speciesof plants in the Ranunculaceae, closely related to " Ranunculus". The common name is globeflower or globe flower. They are native to the cool temperate regions of the Northern Hemisphere, with the greatest diversity of species in Asia, and usually grow in heavy, wet claysoils.
They are mostly
herbaceousperennials with bright yellow flowers, though some have orange to lilac coloured flowers. The name "globe flower" refers to the petals of "T. europaeus" which are curved over the top of the flower to appear like a spherical globe; however, many of the other species have more open, flatter flowers.
All "Trollius" species are
poisonous when fresh to cattleand other livestock, but their acrid taste means they are usually left uneaten. They are, however, used as food plants by the larvae of some Lepidopteraspecies including Silver-ground Carpet.
Some species are popular ornamental flowers in
horticulture, with several cultivars selected for large and brightly coloured flowers.
